I did once encounter a site in the early 2000s that wouldn’t let me use a password because it was already in use by someone else. I was too young at the time to realize how bad that was, but I remember thinking it didn’t make sense.
It MIGHT not be as bad as you think. If the UI was just terrible at communicating and what it actually meant was, “that password is in our database of known compromised passwords,” then that would be reasonable. Google does this now too, but I think they only do it after the fact (e.g. you get a warning that your password is in a database of compromised passwords).
Can confirm that Google will do this for you. Also, I switched to Bitwarden and Firefox last year so most of these passwords have either been changed or I haven’t been on the site in years and don’t much care and im not actually this exposed anymore 😂😂
